Question

convert each H30+ Concentration to a pH value

a. 3.4 *10^-3 M

b. 4.37 *10^-13 M

Answer 1

@Data_LG2

Answer 2

now how would i do this

Answer 3

From the steps that I told you before, only do step 1 :)

Answer 4

\(\sf pH=-log[H^+]\)

Answer 5

ok

Answer 6

so -log( 3.4* 10^-3)

Answer 7

would that be how to set it up

Answer 8

yes

Answer 9

it is 2.468521083

Answer 10

right

Answer 11

yes :)

Answer 12

thanks

Answer 13

how about the 2nd one? you get it?

Answer 14

yes i got it

Answer 15

what about this one.

calculate the H30 + concentration from the pH 1.90

Answer 16

how would i do this

Answer 17

so from [H+] to pH is : \(\sf [H+]= 10^{-pH}\), replace pH with 1.90

Answer 18

.01258

Answer 19

yep!

Answer 20

so is this the anwer

Answer 21

but is wants ________*10^M

Answer 22

then change it to scientific notation, 0.01258 is same as \(\sf 1.258\ x\ 10^{-2} M\)

Answer 23

THANKS
